[antlr-interest] TreeParser doubt

[cintyram]

hi,
 i had a tree parser lilke this ..


rule1 : # ( ID ID rule2 ) ;
rule2 : # ( ASSIGN ID ( COMMA ID )* ) ;

but because i have to extract the values of the matched text, 
 into the data structures in the main program i modified the rules as
follows ..

 rule1 
 [ 
   std::string & name  ,
   std::string & value ,
   std::vector<std::string> & list
 ] 
  : #( nam:ID {name = nam->getText() ; }
       val:ID {value = nam->getText() ; }
      { rule2(list) ; }
     ) /// wrong code .. tule2 shud get the tree it should mtch ..
  ;
 rule2
 [
  std::vector<std::string> & list
 ]
  : # ( ASSIGN i:ID{list.push_back(i->getText() );}
       ( COMMA id:ID {list.push_back(id->getText() );}
       )* 
     )
  ;


as stated in the comment, rule2 has to be passed the tree it is
supposed to match, if used as a function .. 
so what should i do now?
Thanks in advance
cheers
ram
